What is Companion Planting and How Does it Work?

At its heart, companion planting is about creating a diverse garden ecosystem where plants perform multiple functions. This strategy involves positioning different species close together so that they may offer mutual benefits, such as pest control, improved pollination from beneficial insects, and enhanced growth. It’s a harmonious approach that underscores the interconnectivity of the living landscape.

Historical Roots: From the Three Sisters to Modern Gardens

Companion planting isn’t a new fad; it has sustained cultures for centuries. A notable example is the “Three Sisters” technique practiced by Native Americans, intertwining corn, beans, and squash. Each plant in this triad supports the others — corn provides a structure for beans to climb, beans bring nitrogen to the soil to benefit all, and squash with its broad leaves shades the soil, reducing weed growth and preserving moisture.

The Science Behind Plant Relationships and Pest Management

Understanding the science of companion planting can turn your garden into a natural pest deterrent. For example, blooms of chrysanthemums contain pyrethrins, naturally deterring many insects, and alliums release compounds from their roots that many pests find unpalatable. By studying these phenomena, gardeners can effectively utilize plants’ inherent pest management capabilities, reducing the need for artificial interventions.
